Tests of CP symmetry in entangled hyperon anti-hyperon pairs at BESIII
Tests of CP symmetry in entangled hyperon anti-hyperon pairs at BESIII
Decays of charmonium into hyperon and antihyperon pairs provide a pristine laboratory for exploring hyperon properties, such as their polarization and decay parameters, and for conducting tests of fundamental symmetries. This brief review highlights the significant progress made in precise tests of CP symmetry at BESIII using entangled hyperon-antihyperon pairs, …
